Diethyl methylphosphonate is used as a precursor for the synthesis of gem-difluroalkenyphosphonate via reaction with alpha-trifluromethylstyrene. It is also used in the synthesis of phosphonylated peptides, fluoroalkyl alpha- and beta-aminophosphonates, pyridone alkaloids with neuritogenic activity and lipophilic meropenem-derived prodrugs.
For synthetic applications of the lithio-derivatives of esters of methanephosphonic acid, see Dimethyl methylphosphonate, A14268.
Dialkylation has been used in the synthesis of cyclobutanephosphonates which are intermediates in the synthesis of 3-phosphonocyclobutyl amino acids: J. Chem. Soc., Perkin 1, 493 (1997).
Reaction of the lithio-derivative with dialkyl cyanamides gives, instead of the expected 2-phosphorylacetamide, a rearranged N-phosphorylated amidine: Chem. Commun., 609 (1998):
